Signs of Roof Aging in New Jersey Homes
Recognizing the signs of an aging roof can help homeowners address issues before they lead to significant damage. In New Jersey’s climate, be on the lookout for these indicators:
Visual Indicators
- Curling or missing shingles: Heat and moisture can cause shingles to curl at the edges or corners. Missing shingles leave your roof vulnerable to leaks.
- Granules in gutters: As asphalt shingles age, they shed granules. If you notice an accumulation in your gutters, it’s a sign your roof is deteriorating.
- Visible sagging: A sagging roofline can indicate structural issues, often caused by long-term water damage or poor ventilation.
- Daylight through roof boards: Check your attic for any spots where daylight is visible through the roof boards. This is a clear sign of holes or severe deterioration.
- Algae or moss growth: While sometimes just a cosmetic issue, extensive growth can trap moisture and accelerate shingle deterioration.
Structural Signs
- Leaks in the attic: After heavy rain or snowmelt, check your attic for signs of water infiltration.
- Water stains on ceilings or walls: These can indicate a leak that may have been ongoing for some time.
- Paint blistering on interior walls: Moisture seeping through the roof can cause interior paint to bubble or blister.
- Exterior paint peeling: Moisture escaping through the roof can also affect exterior paint near the roofline.
Energy Efficiency Changes
- Unexplained increases in heating or cooling costs: A failing roof can lead to poor insulation, causing your HVAC system to work harder.
- Uneven temperatures throughout the house: This could indicate that certain areas of your roof are allowing more heat transfer than others.
